    Hey all,

    I have this surround setup -- and am extremely happy with it:

    http://cerwinvega.com/products/homea...ies/avs51.html

    Now, My question is -- I am trying to properly set the crossover in the receiver, and I want to find out what the Hz range is for the main loudspeakers. The spec sheet give an over all range -- but that includes the sub which starts at 35Hz -- so that doesn't help... I would like to find out so i can set my xover to about 10Hz above the lowest limit of the mains.... if i called the company, would they have those specs?

    Thanks,

    Matt

    With a 4" driver, I'd say it's safe to say they are somewhere between 80Hz and 100Hz. You don't want to set your x-over so close to that point because the speaker will roll off quicker than the x-over will, creating a gap/dip. I'd try a 100Hz or 120Hz x-over.

    The easiest way to find out is to get Avia or VE and run the singnal sweep for your speakers. When they drop off, you know you reached the limit.

    you could use a spl meter and some test tones to determine where they roll off at and to find a good crossover point.

    VE doesn't have a signal sweep, or do you mean DVE?
